METAL-WORKING I MACHINERY.

Specification of Letters Patent.

Application filed May 9, 1911. Serial No. 626,030

To all whom a may wm Be it known thatI, CLARENCE O. CRALEY, a citizen of the United 'States, residing at Harrisburg, in the county of Dauphin and State'of Pennsylvania, have invented new and useful Improvements in Metal-Working Machinery, ofwhich the following is a specification. I

The present invention relates to metal working machinery, in which great accuracy is necessary, and the object is to prodrawings. In the embodiment illustrated, a drill l6 experimenting.

vide a simple and practicable means for rapidlyand accurately laying out, machining; and inspecting toolsand the like, such.

with exactitude at the time it is laid out and performed. Furthermore it can be accom-. plished with expedition and without mere A simple embodiment of-the invention is illustrated in the accompanying drawings, wherein v Figure 1 is a side elevation in a conventional manner of a machine having the novel mechanism. Fig. 2 isa detail-view on an enlarged scale, showing the. gaging structure. Fig. 3 is a longitudinal sectional view on the line 3-3 of Fig. 2. Figs; t, 5 and 6 are respectively cross sectional views on the lines ie-4:, 5-5 and 6.-6 of Fig. 2.

' Similar reference numeralsdesignate corresponding parts in all the figures of the press is disclosed, and includes a work supporting table, in which a rotatable member 7 carries a transversely slidable member 8 on which is mounted another sliding memher 9 that moves at right angles to the member- 8. Suitable means 10 are provided for effecting the movements of the members 8 and 9. As thus far described, the structure is well known, and may be varied to a considerable degree. Each set ofmembers 7 and 8 and 8 and 9 are provided with means for.

gaging'the "amount of movement that may fixed against accidental movement.

, be given to them, and these gaging means permits a great amount of movement, while indicating such amount of movement to an exceedingly smalldegree, as for instance, the thousandth of. an inch. v

Inasmuch as the gaging mechanisms for both sets of members are the same, a description of one'is believed to besufiicient for both, and one of the same in detail is illustrated in Figs. 2-6 inclusive. Thus in Fig. 2, the member 8 may be considered as the supporting member, and, the member 9 as the work-carrying member. Said'member 9 is provided with a longitudinal substantially T-shaped slot 11, formed in'an over-' hanging portion of the member 9, as will be clear by reference to Fig. 4. In this slot is located the head 12 of a securing bolt 13,

which bolt supports a bracket 14- that can thus be 'moved to different positions on the. member 9 and fixed at'such positions. The

bracket 14 is provided witha socket 15, in

which is slidabl mounted a stop head 16 having a stem 1 that projects through the rear side of the bracket where it is threaded to receive an adjusting nut 18. A spring 19, interposed between the head 16 and the rear wall of the socket, serves to urge said head to projecting relation. The lower corner of the bracket is split, as shown at 20," and one or more binding screws 21 are passed therethrough. .With. this arrangement, it will be evident that if the screws 21 are loosened, the head may be positioned with respect to the bracket 14, as desired, and.

when the desired position has been obtained by setting the screws'21, the head will be supporting member 8 is also provided with I a suitable bracket 22 that carries a microm- Zeter head 23. This head may be of any well known form, and includes an adjustable stem 24 that codpe'rates with the. end of the stop head 16. The bracket 14:.is provided Patented Oct. 31, 1911.

The

with an arm 25 having an upturned end 26, r

in which is formed a V-shaped .seat 2?. Pivoted to the other bracket 22 is another arm 28 having an upturned end 29 provided with a V-shaped seat 30. A retaining spring 31 extends over this seat. The pivotal mounting of the arm 28 is shown at 32, and it will be noted that in theform .of construction shown, and as illustrated especially in Fig. 3,'the outer corner 33 ofthe arm 28 is square and is borne against by a spring 34 securedto the bracket 22.

in using the mechanism, the work is first clamped upon the member 9 in the desired position, and the gage elements, comprising the micrometer head 23 and the stop head 16, are placed in associated position, and are arranged inthe desired relation. Assuming that holes are to be drilled at predetermined distances apart, after the first hole has been made, 'the member 9 is moved the desired distance, and simultaneously with this movement,- the micrometer head is also operated, so that the distance in one direction can be determined with the greatest accuracy. lii necessary, the members 8 and 9 together may be moved transversely of the member 7, and- -in iikemanner, the positlon can be determined by the gaging mechanism employed between these two members. lit the distance is so greatthat the micrometer head 24% will be carried out of coaction with the stop head 16, spacing devices, in the form of pins 35, of predetermined standard lengths, may be interposed between said stem and head, as illustrated in Fig. 2. For example, pins, of one, two, three inches, etc. may be empioyed. Tlhe pin desired is placed in the seats 27 and 30,-and is retained by the spring 31.

I iVhen the pin is not employed, it will be evident that in the structure shown, the arms and 28 may interfere, but inasmuch as the'arm 28 is pivotally mounted, it can be swung to the position illustrated in dotted lines in Fig. 8, whereupon the parts 24 and 16 can be brought into operative position, and the stem 24 can pass freely through. the seat .27 of the arm 25. When in position, the pin has free sliding movement in the seats, so that it will adjust itself to proper position. As already explained, this gaging mechanism can be employed on either or both of the sets of members 7 and 8 and 8 and 9. in the claimstherefore, the term inirlvcarrying means is intended to be broad enough to cover the parts 8 and 9 when they move together with respect to the member TI, and in like manner the term supportmg member is mtended to be broadenough to include the member 8 when the member 9 per se acts as the workcarrying member, and is moved with respect to the member 8. I

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be un derstood that various changes in the size, shape, proportion and minor details of con struction, may be resorted to Withoutdeparting from the spirit or sacrificing any of the advantages of the invention. For example, the handle or micrometer head may be placed on either side to suit the convenienceiof the operator, and the micrometer may be graduated so that a finer adjustment 1.
